AFAIK, president of Wikimedia Russia is Vladimir Medeyko, not Stanislav Kozlovskiy. And "wikipedia.ru" seems to be squatted.
I have to admit that cyber-squatters have become more inventive. They are making NPOs for squatting domains of other NPOs.
Stanislav Kozlovskiy is a vice-president of Wikimedia Russia.
It is still not clear whether this is hoax or somebody really filed a lawsuit.
